I have been searching high and low to see what is "normal" for these levels to do. I look at my flow sheet from my IUI's and they fluctuate on there, but in a BFP cycle, what do your E2 and Prog look like on day 4 & 7. did you have any indicators on these days that you didn't have when you had BFNs? I was on follistim on my IUI cycles, and triggered with Ovridel. Thanks for any insight you might have...
